An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-3957 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-3957/ (Markdown: https://insights.sbomify.com/CVE-2016-3957/index.md)","id":"CVE-2016-3957","markdown":"https://insights.sbomify.com/CVE-2016-3957/index.md","name":"CVE-2016-3957","record":{"aliases":["GHSA-p6rg-cchx-f5x4","UBUNTU-CVE-2016-3957"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"web2py framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by exploiting unsafe pickle deserialization in web2py session cookies if the encryption key is known.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"web2py","vendor":"web2py"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The secure_load function in gluon/utils.py in web2py before 2.14.2 uses pickle.loads to deserialize session information stored in cookies, which might allow remote attackers to execute arbitrary code by leveraging knowledge of encryption_key.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2018-12-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-12-19T16:55:03Z","kind":"github_poc","ref":"https://github.com/sj/web2py-e94946d-CVE-2016-3957","stars":0,"title":"web2py/web2py @ e94946d"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Deserialization in n/a","id":"CVE-2016-3957","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2016-3958"},"packages":[],"prev":{"headline":"npm Token Leak in npm","id":"CVE-2016-3956"},"products":["n/a"],"published":"2018-02-06","related":[{"cvss_score":9.8,"headline":"Command injection in web2py","id":"CVE-2023-45158","kev_date_added":null,"published":"2023-10-16"},{"cvss_score":9.8,"headline":"web2py remote code execution via hardcoded encryption key in session.connect function","id":"CVE-2016-3953","kev_date_added":null,"published":"2018-02-06"},{"cvss_score":9.8,"headline":"web2py is vulnerable to password brute-force attack","id":"CVE-2016-10321","kev_date_added":null,"published":"2017-04-10"},{"cvss_score":8.8,"headline":"Web2py Cross-Site Request Forgery vulnerability","id":"CVE-2016-4808","kev_date_added":null,"published":"2017-01-11"},{"cvss_score":7.8,"headline":"Information disclosure in n/a","id":"CVE-2016-3952","kev_date_added":null,"published":"2018-02-06"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2016-4806","kev_date_added":null,"published":"2017-01-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by exploiting unsafe pickle deserialization in web2py session cookies if the encryption key is known.","url":"https://insights.sbomify.com/CVE-2016-3957/"}
